I use 3 beacons, and took the code from this site
http://developer.radiusnetworks.com/ibeacon/android/samples.html
the code works until I don't want to explore the region which is in the method like in this line:
Log.i(TAG, "I just saw an iBeacon for the firt time!" + region.getMajor().toString());
, this how looks my activity,
public class Monitoring extends Activity implements IBeaconConsumer {
protected static final String TAG = "RangingActivity";
// instance of beacon manager which menage the beacon action
private IBeaconManager iBeaconManager = IBeaconManager.getInstanceForApplication(this) ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// bind with implemented IBeaconConsumer
iBeaconManager.bind(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public void onIBeaconServiceConnect() {
iBeaconManager.setMonitorNotifier(new MonitorNotifier() {
@Override
public void didEnterRegion(Region region)
{
Log.i(TAG, "I just saw an iBeacon for the firt time!" + region.getMajor().toString());
}
@Override
public void didExitRegion(Region region) {
Log.i(TAG, "I no longer see an iBeacon");
}
@Override
public void didDetermineStateForRegion(int state, Region region) {
Log.i(TAG, "I have just switched from seeing/not seeing iBeacons: "+state);
}
});
try {
iBeaconManager.startMonitoringBeaconsInRegion(new Region("myMonitoringUniqueId", null, null, null));
} catch (RemoteException e) { }
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
iBeaconManager.unBind(this);
}
}
I wanted to use it to show message if the app is in the region of particular beacon.
